Abstract

An exhaust duct (20) for a gas turbine engine has an annular inlet conduit (26) having an inlet axis (A1). At least two outlet conduits (30,32) branch off from the inlet conduit (26) along respective outlet centerlines (A2,A3) that are distinct from one another. The outlet centerlines (A2,A3) when projected onto a projection plane perpendicular to the inlet axis (A1) are spaced apart from the inlet axis (A1) so as not to intersect the inlet axis (A1).
